What are the speed regulation methods of gear reducer motors?

Geared motors are used in many devices for speed regulation due to their high reliability, versatility, simple maintenance and long service life. So what are the ways to adjust the speed? Here, I would like to tell you that there are two speed regulation methods, stepwise speed regulation and stepless speed regulation, which will be introduced one by one below.

First, let's look at the step speed adjustment. Step speed regulation is a simple and economical speed regulation method, but this speed regulation method is only suitable for 2kw and occasions that do not require much starting.

Its speed regulation has only two gears, so the speed regulation range is relatively narrow. There are also some gear reduction motors that can reach the speed regulation range of three gears, but only in some special cases will the speed regulation of the third gear be used. When adjusting the speed, a geared gearbox is required.

Secondly, let's look at the stepless speed regulation, which can be divided into two methods: mechanical speed regulation and electrical speed regulation.

Mechanical speed regulation is to add a mechanical stepless speed regulation device where the motor and gearbox are connected. The advantage of this speed regulation method is that the operation is relatively simple, the speed regulation stability is high, and it can be used in harsh environments, but it also has the disadvantage that the speed regulation range is relatively small and requires frequent maintenance.

The electric speed regulation method can realize rotor resistance speed regulation and cascade speed regulation of asynchronous motors, as well as voltage speed regulation and speed regulation of DC motors.

As we all know, the speed regulation methods of geared motors can be divided into two main types, namely stepwise speed regulation and stepless speed regulation. These two speed regulation methods have their own advantages and disadvantages and scope of application. They can be grouped together when adjusting the speed. Choose the actual situation.
